Many people think that promiscuity is morally acceptable, but rape and pedophilia are heinous. I argue, however, that the view of sexual ethics that underlies an acceptance of promiscuity is inconsistent with regarding (1) rape as worse than other forms of coercion or assault, or (2) (many) sex acts with willing children as wrong at all. And the view of sexual ethics that would fully explain the wrong of rape and pedophilia would also rule out promiscuity. I intend this argument (...) neither as a case against promiscuity nor as either a mitigation of rape or a partial defense of pedophilia. My purpose is to highlight an inconsistency in many people's judgements. Whether one avoids the inconsistency by extending or limiting the range of practices one condemns, will depend on which underlying view of the ethics of sex one accepts. (shrink)
